It is NOT the same tube. The 6P14P-EV is an EL84 equivalent with a little more power. The amp you have however, is designed for the 6P15P-EV or SV83. You can try some of the 6P14P-EV in your amp and see if you like them better. This tube does not benefit from the Hazen Grid Modification that makes the 6P15P-EV's sing.

Thanks, I was offered these tubes as a direct replacement so I'm glad I asked....Proffessional tube-stores obviously like to sell tubes, no matter if the customer askes for a specific tube [the 6p15p-ev].THANKS AGAIN.Nico

I have a Zkit-1 and a second similar home-brew amp (that will be at Decfest this year) that loves the 6p15p and hates the 6p14p. The difference is night and day. Lots more power from the 6p15p and a much nicer sound. Then, a while back, I worked on a Taboo, and that amp was just the opposite...got more power and sounded better with the 6p14p. So, pick the one you like best and go with it.
